Abstract: The bond in a grinding wheel cements the abrasive grains together, Among other factors,
the bond plays a predominant part in the grinding wheel performances and on the quality of
grinding results. This paper presents a literature review on organic bond grinding wheels. It
discusses the characteristic of the bond and the grinding performances of the two mainly types of
organic bond [1] grinding wheels: the resin bond grinding wheel and the soft-elastic grinding wheel.
This paper provide a conclusion of the studying state of organic grinding wheel, which new
studying can draw lesson from.

Abstract: To improve the machining efficiency as well as surface roughness, a resin-bonded fixed abrasive tool is developed for lapping process of stainless steel substrate. To optimize the lapping ability of the fixed abrasive tool, the influences of bond material concentration on the mechanical properties of fixed abrasive lapping tool, including structure hardness, shear strength, the water-absorbing capacity and modulus of elasticity in compression are investigated. The micro structure of tools is also observed. Tools made of #1000 SiC abrasive and resin with different concentrations is employed in the tests. It is found, the hardness, shear strength, and modulus of elasticity in compression reach highest value, as the 35%wt bond material are used. The water-absorbing capacity increases as the bond material concentration decreases. It is judged from the SEM images that the number of pores in tool with 35%wt bond material is at the most.

Abstract: Two kinds of vitrified bonds, bond L (low temperature bond) and bond G (high strength bond), were blended by ball-milling in producing diamond wheels. Proper Sintering techniques were employed by analyzing properties of the wheel through DSC testing and fracture strength. The wheels were applied in machining PDC in comparison with similar product on market. It showed that the blended bond reached its highest fracture strength when bond L amount was about 20wt~24wt%; combination of this two kinds of vitrified bonds would improve the wheel’s comprehensive properties by raising its fracture strength to 89MPa when bond L takes up 22wt%; service life of wheels prepared by this blended bond was 30~50% longer than similar market product and efficiency improved by more than 20%.
